My Axon II is not being recognized by my laptop or my desktop. All the drivers are installed. First, I connected to my laptop via USB. It worked great and displayed as Siliconlabs something. Then I wheeled my robot across carpet (possible ESD buildup?) to my desktop and connected it to my desktop. I got nothing. I don't know what's going on, but I pray I didn't destroy my Axon due to ESD. Anyone care to help. Could I get around this issue by purchasing ISP AVR Programmer?

Thanks for reading

When I apply power to it, the Marquee turns on and blinks so that's a good sign. Do you think its the bootloader or the AVR chip responsible for the USB to serial?

A few questions so I can narrow the problem and help you fix it:

- Does it still work on the laptop?- Did you program with the USB bootloader before?- Did you ever plug anything into the pins '3.3V OUT'? (even by accident)- Does USB work when nothing else is plugged into the Axon II?- Did your laptop/PC give you any USB errors?- What is your battery voltage?- When you 'wheeled it over', what specifically does that mean? (a serious question)- What devices are attached to your robot, and to what pins?

Go to:Control Panel -> System -> Hardware (tab) -> Device Manager (button)What do you see for USB?(this assumes you have XP, but may be a little different depending on your OS)

ESD should not be a problem.

Where did you plug the 12V into? Are you using single or dual power mode?
